Tire building machine having means advancing a plurality of drums through a plurality of assembly stations

ABSTRACT

A fully automatic machine for producing &#34;green tires&#34; or unvulcanized tire carcasses, especially suitable for making tubeless tires. The machine comprises a plurality of interconnected and dependent assemblies or stations where specialized operations, normally done semi-automatically or by hand, are carried out by mechanical devices acting in sequence. The machine includes a plurality of conventional tire building drums continuously moving between horizontally disposed, stationary table assemblies where innerliner and chafer strips, and first and second ply material are successively wrapped on the drums as they move across the table on which the material is positioned. The wrapped drums from these assemblies, are sent to turret units where they are accurately positioned for recieving beads, tread cushion, stitching, strips of whitewall, if required, and are discharged from the collapsed drums for removal and storage. The stripped drums, or drums from which tires are removed, are automatically expanded and recycled through the assemblies for building more tire carcasses.
